FAQ
What is the conversion factor from therm to kJ?
1 therm equals 105480.4 kJ. To convert, multiply the value in US therms by 105480.4.
How do I convert 1 therm to kJ?
1 therm = 105480 kJ. For any value, multiply by 105480.4.
How do I convert kJ back to therm?
Divide by the same factor — or equivalently, multiply by 9.480434e-6. So 1 kJ = 9.48043e-6 therm.
When would I need to convert US therm to kilojoule?
Energy conversions are needed when reconciling fuel/electrical billing, calculating thermal duties, and aligning calorimetry or HHV/LHV figures across data sources.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
